Dynamic (enum) filters in a template grid

I'm searching for dynamic filter options (based on entity enum's) to filter my template grid. I hope I'm overlooking the basic functionalities, but thus far I haven't found a way to filter the database data in a template grid. Alternatively, I could make it a list view and, by help of CSS, make it two columns, have the same styling and use the addon 'list view controls'.. But as the correct widget is a template grid here, I'd like to keep using the template grid. So in short: How can I get enum filters in my template grid?

What data source are you using? You should be able to right click above the search button and click "add search field". The one you would want is "Drop-down"


If you are using data source over an association, search filters are not allowed. You could change it to xpath and add the same association as a constraint. 


Hope this helps!
